I need a 3-groove water pump pulley for a '60 Electra with A/C. Mine is bent enough to cause high RPM vibration, don't think the pump will take much of it. I have looked everywhere, called all the Buick guys, junk yards, etc. Can these be straightened? Was it used on any other car? Part # 1187732 Any one have any ideas for modifications, substitutions?
